HAND O'PE'RATED PEESSING TOOL.

. Application filed February 20, 1922. Serial no. 538,140.

. T ll whom, it may concern.

Be it known that I, HENRY G; Lewis, a

citizen of the United States residing at Charlestomin the county oflianayvha and 1 State of West Virginimlmve invented anew and usefulHand-Operated Pressing Tool, of

directions.

()ne of the objects of the invention is to provide a hand operated device, having means whereby pressure may be applied'to an article by slmultaneously actuated, rela tively movable members, arranged in quadrilateral relation. -A tlurtherobject is to providepressure members so mounted that they arecaused to open or close, by simultaneous, coextensive, relative movement, effectedby suitable means, said; members being arrang ed" inquadrilateral relation, to insure the production o'i-an openingof similar contour I of increased or diminished size, determined.

by the direction of relative movement. A further ob ect is to provide means by which the parts maybe so adjusted, as to provide an opening of true square cross seetiomor of oblong section, as maybe desired. object is to provide pressure members normally movable inunison, and means whereby one member -mayube* temporarily displaced, to permit of theinsertion or removal of an article, to be engaged by said members.

The invent-ion will be" hereinafter fully torthand particularly pointed out in the claims.

. in the acompanying drawingz Figure 1 is a side elevation, illustrating a tool constructed in accordance with the in vention, with the parts adjusted to' provide an opening" of maximum diameter. Figure 2 a similar vie v illustrating the relative positions of the partsjnecessary to produce an opening 1 or smaller diameter. ""gure 3 a detail sectional view of the carriers, member illustrating; the manner of mount ing the pressure members.

Referring to the drawing, 10 designates an upper carrier, and 11 a lower carrier, each being provided with a slotted arm 12, WhlCll engages a guide pin 13, carried by ahand bar 14;. The tWo handle bars are pivotally connected to each other at 15, and also pivotally connected to the respective arms 12, as indicated zit-16. The arrangement is such A further thatas 'thehandle bars 1% are moved toward or from each other, a corresponding relative movement is imparted tolthe upper and lower car-11ers l0 and 11, respectively.

lheupper carrier is provlded With a casi 1;, 111g 11, which maybe tor-med in any suitable manner, tor instance by means of walls which embrace the carrier member, and. are

securedthereto in suitable manner. Said oasis provided ivitha chamber,in Which is mounted anormally fixed adjustable 1ne1nber, 18, and a normally slidable member 19,

said members having abutting longitudinal faces. The member 18 is preferably L- shaped, i. e, is provided with a lateral extens1on 20, to provide a pressure surface of maximum area. flheupper end of the member-'18 "isengaged by an adjusting screiv 21, \vliicli' also engages a eomplemental threaded opening in the top of the casing 17, the projecting end being provided with a suitableen'largement 22, by means of which the screw may be operated. A lock nut 23 serves to hold the screw in any adjusted position. The member 19 is nor mally presseddownwardly by means of a spring 24, thetensiori] of which is regulated by a-screiv 25, working-in the top of the casing 17. i

The upper end of the lower carrier 11 is provided With. a pressure member formed by the face 26, parallel with the underpressure face of the member 19, and its lateral extension, and disposed at right angles to the longitudinal median line o'lthe slidable member 19, the lower end of said slidable member abutting against sald pressure face,

whereby movement of said member 19 in one direction is limited. member il is also provided With a casing 27, which may be. termed in the same manner casing; 17, and mounted therein is a spring pressed pressure member 28, disposed at right angles to, the face and abutting against the Working face of the lateral extension 20. Saidmember 28 is normally held in yieldable engagement'ivith said lateral extension, by means of a spring-"29, the as sion of which is regulated by screw 30.

In practice, the springs and 29, in ad ditlon to their other functions, react against the carriers 10 and 11, through the members 19 and 28, to normally effect a yieldable soparatlon of said carriers, and a corresponding; separation 01' the ends of the handle bars 14.

o ward lower carrier space.

In order to provide an independent movement of one of the pressure members, the spring pressed member 28 is provided with a projection 31, extending through a slot 32 in the casing 27, which projection is engaged by one end of a bell crank lever The other end of the lever 33 is positioned sufficiently close to one of the handle bars to be reached by the forefinger of the operator. By pulling back upon the free end of the bell crank lever 33, the member 28 is withdrawn against the tension of its spring, leaving an opening in one side of the space "normally formed by the pressure members.

When the lever 33 is released, the spring 29 returns the member 28 to its normal position.

In operation, the spring 24% normally forces the member 1.9 outwardly, with its end in contact with the pressure face 26, of the lower carrier. Likewise the spring 29 normally forces the member 28 outwardly into contact with the under side of the lateral extension 20, of the fixed member 18. Thus, as shown, the lower end of the member 18, the pressure face 26, and the contiguous side faces of the slidable members 19 and 28, provide a quadrilateral space formed by four pressure members. As illustrated in Figure 1, the space is shown of the maximum dimensions possible with the particular tool. As the ends of the handle bars are brought toward each other, the pressure member 26 moves toward the member 18, and at the same time the members 19 and 28 are forced into their respective casings. Simultaneously with their inward movement the ends of members 19 and 28 will travel along the pressure face 26, and the under side of the member 18, respectively, thereby changing the "dimensions of the space, but always retaining the same quadrilateral contour at all positions of adjustment. To all intents and purposes the member 18 is normallyfixed and the adjustment of the other pressure members is effected with respect to a fixed position P, on said fixed member, namely, the lowermost corner thereof adjacent the member 19. By actuating the bell crank lever 33, the member 28 is withdrawn, and the article to be pressed or shaped may be inserted into or removed from the space formed by the members 18,19 and face 28. The lever 33 is then released and the member 28 will spring to its normally closed position, and cover the open side of said By moving the ends of the handle ii-ars toward each other, the various pressure members are caused to simultaneously adjust themselves, until they engage the article and squeeze it on all four sides simultaneously, bringing said article to a quadrilateral cross section.

As shown in full lines in the drawing, the

quadrilateral space is an approximately true square. If it is desired to change the contour of the space to oblong shape, the desired adjustment may be effected through the medium of the adjusting screw 21 as shown in dotted lines, Figure 2. By means of this arrangement, the normally l'ixed member 18 is adjusted to a greater distance from the face 26, than shown in full lines, thereby producing an oblong space, the dimensions of which will vary in conformity with the relative movement of the carriers 10 and 11, the adjustment of all of the parts being simultaneous and coextensive.

The advantages of the invention will be readily understood by those skilled in the art to which it belongs. It will be particularly noted that by means thereof, a hand tool of simple construction is provided, the same having means whereby pressure may be applied to an article by simultaneously actuated, relatively movable pressure members, arranged in qu-Lulrilateral relation. Another advantage resides in the fact that the parts are so mounted in the carriers and the handle bars, that the pressure members are caused to open or close. by simultaneous coextensive relative 11love ment, eiiected through the medium of said handle bars. An important advantage is that the normal contour of the space formed by the pressure members may be changed. and that although all of the members are normally so engaged as to be simultaneously adjustable, one of them is provided with means by which it may be indepemlently actuated, to temporarily displace it for the insertion and removal of the article to be operated upon.
